APPARATUS FOR PROVIDING WOODEN SHELLS OR OTHER ARTICLES WITH LONGITUDINAL OPENINGS OR DUCTS OF POLYGONAL CROSS-SECTION` SPECIFICATION forming part of Letters Patent No. 679,597, dated July 30, 1901. Application filed September 6, 1900. Serial No. 29,184. (No model.)

To @ZZ wwm t may con/cern:

Be it known thatI, WILLIAM BROWN, a subject of the Queen of Great Britain, residing at Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Apparatus for Providing TVooden Shells or other Articles with Longitudinal Openings or Duets of Polygonal CrossSection; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, which form a part of this specification.

This invention has reference to a novel apparatus or machine for providing wooden shells, and especially such as are ordinarily employed for use in baths and between the baths and printing-machines to roll or wind the web thereon and for other uses in processes of bleaching or dyeing, with an angular hole or duct which will be of a polygonal cross-section and will extend longitudinally through the entire length or partly through the length of the shell.

This invention therefore has for its principal object the production of a simply-constructed and effectively-operating mechanism for the purposes above stated,with a view of more quickly and more cheaply providing the wooden shell with a longitudinally-arranged and polygonally-shaped duct.

My invention therefore consists in the novel construction of apparatus hereinafter described; and, furthermore, the invention consists in the several novel arrangements and combinations of the various parts, as well as in the details of the construction thereof, all of which will be more fullyset forthin the accompanying specification and then finally embodied in the clauses of the claim7 which form a partof this specication.

This invention is clearly illustrated in the accompanying drawings, in which- Figure l is a front view of one form of apparatus embodying the principles of my invention, and Fig. 2 a longitudinal vertical section of the same. Fig. 3 is a longitudinal vertical section, on an enlarged scale, of the upper portion of a tubular standard, a gang of saws or cutters connected therewith, and mechanism for operating the said saws or cut ters. Figs. .tand 5 are atop and bottom View, respectively, of the upper tubular section of said standard. Fig. G is a horizontal cross-` section of the apparatus, taken on line 6 6 in Fig. 2; and Figs. 7 and 8 are horizontal crosssections taken, respectively, on lines 7 7 and 8 8 in either of Figs. 2 or 3. Fig. 9 is a horizontal cross-section of a wooden shell provided with a longitudinal duet produced by a gang of saws or cutters, illustrated in the previously-described gures of the drawings; and Fig. lO is a longitudinal vertical section of a portion of the wooden shell.

Similar numerals of reference are employed-` in all of the said above-described views to indicate corresponding parts.

In the said drawings, in Figs. l, 2, 9, and l0 the numeral l indicates the shell, of wood,

which is to be turned down on the dotted line` 5' (indicated in Fig. 9) to provide a cylindrical or roller-shaped shell; but this is not absolutely necessary,and this feature is sometimes varied.

In the production of the wooden shells for the purposes above stated the shell is first provided with a cylindrical bore which is turned or bored out in the usual manner, and that the finished shell may be arranged and suspended on the receiving core, which is usually of a square shape in cross-section, but which may be of any other suitable polygonal cross-section, portions of the cylindrical outline 3 of the bore 2 are cut away by' means of my novel construction of apparatus hereinafter fully set forth to produce angular recesses 4, which extend from end to end of the shell and by means of which the shell can be lfitted on the core,which also has a polygonal cross-section.

. The apparatus for providing wooden or other suitable shells with boreshaving a polygonal cross-section consists, essentially, of a base 5 and topo, both of which are preferably provided with cleats 7 for strengthening said base and topand preventing their becoming warped when made of wood. Itis not essential, however, that the base and top are made of wood, for metal plates may be em- IOO ployed, if desired. The said base'and top are usually connected by means of suitable tierods 8 and nuts 9, arranged on screw-threaded 4.perdons of the said rods, substantially as represented in Figs. 1 and 2. Secured in any suitable manner against the under side of the base 5 are bearings 10, (see Fig. 2,) in which there is a main shaft 11. This shaft is provided at its vone end with a drivingpulley 12 and upon its other end and beneath a centrally-disposed opening 14, 'in the central portion of the base 5, with a miter or bevel gear 13, substantially as and for the purposes hereinafter more fully specified. Upon thesaid base 5 is a tubular standard 15, which is provided at or near its lower end with a flange 16, which rests upon the base 5 and is secured in position by means of bolts or screws 17, substantially as illustrated.A The lower end portion 18 of this standard l5 is also securely fitted in the said opening 14 in the base 5, and the said standard is thereby held in a fixed position for the reception of a vertical spindle 19. This spindle is provided at its lower end with a miter or bevel gear 21, which meshes with the bevel or miter gear 13 on the main driving-shaft 10. The said spindle 19 is also rotatively arranged in any desirable number of bearings in suitable plates 20, which are secured within the said tubular standard 15in any desirable and well-known manner. Upon the upper end of the said spindle 19 is secured in any well-known manner a miter or bevel gear 22. These bevel-gears are secured upon the said ends of the spindle 19 in the usual mannerof securing such parts together. The said tubular standard- 15 is provided at its upper 'end with an annular shoulder 23 and has fitted thereon a tubular section 24, which is in like manner provided at its upper end with an annular shoulder 2.5 for the reception of a retaining-ring 26, all of which is more clearly represented in Fig. 3 of the drawings.

As will be seen more especially from an in.

spection of Fig. 3, I have rotatively arranged in oppositely-placed holes 27 in the upper portion ofthe tubular standard 15 a horizontallyarranged spindle 28, which is provided at or near its one end with a miter or bevel wheel 29, in mesh with the bevel or miter wheel 21, secured upon the upper end of the vertical spindle 19, as previously stated. This miter or bevel gear 29 is preferably secured in place upon the spindle 28 by means of a key 34, as shown, so as to rest against a suitable shoulder on the said spindle 28. In order that the spindle 28 may be suitably secured in position in the inner tubular part of the standard 15, I have provided each end of the said spindle with a screw-threaded socket 35, into each of which is screwed a screw bolt or stud 36, the cylindrical heads of which are relatively arranged in the holes or bearing portions 27 in the standard 15, substantially as shown in said Fig. 3. The said screw-bolts 36 also serve to securely arrange in place against the respective ends of the spindle 2S a pair of rotary cutters or circular saws 30 and 31, the said cutters or saws being made to partially project into and through slots 32 and 33 in the said upper portion ofthe'standard 15, as will be clearly evident from an inspection of the several figures of the drawings. In order that the screw-bolts 36 can be properly screwed into the socketed ends of the spindle 28, the latter is provided with a hole 37 for the reception of a'rod'or other means to prevent turning of the spindle, as will be clearly evident; but other means to prevent turning of the spindle when securing the screw-bolts in position may be employed, if desired.

In the upper tubular section 24, which rests upon the annular shoulder 23 of the upper portion of the standard 15, as previously stated, I have secured in any well-known manner a pair of bearing-plates 38. These are provided with holes 39, forming bearings for the end portions 41 of a vertical spindle 40, which is arranged between the said plates 38. Secured upon the said vertical spindle 40, preferably by means of a key 42, is a bevel or miter gear 43, which is in mesh with the gear 29 and is actuated from the latter to cause the rotation of the vertical spindle 40. A second bevel or miter gear 44 is likewise secured by means of the key 42 upon the spindle 40, the said bevel or miter gear being in operative engagement with a bevel or miter gear 45. .This gear 45 is secured upon a horizontalspindle 46, which is provided at its opposite ends with screw-bolts 47, secured in the ends of the said spindle 46 in the manner of the screw-bolts 36, connected with the spindle 28. The heads of these screw-bolts 47 are rotatively arranged in holes 48 in the opposite sides of the tubular section 24, substantially as illustrated in Fig. 7. The heads of the screw-bolts 47 are also made to secure a pair of circular saws or cutters 50 and 51 in position upon the said spindle 46. These saws or cutters project into and through slots 52 and 49 in the cylindrical surface of the said upper tubular section 24, as shown. When viewed from the top,this pair of saws IOO IIO

50 and 51 and the pair of saws 30 and 3l are arranged in Vertical and parallel planes, each pair of' planesbeing at right angles to each other, whereby the saws when the parts of the mechanism just described are operated will be rotated in similarly disposed planes, and should a block of wood or a shell provided with a cylindrical bore, as indicated in Fig. 9, be forced down against the several revolving saws or cutters, then angular corners 4 will be cut longitudinally in the block or shell 1 and an opening or duct of approximately the shape illustrated in cross-section in Fig. 9 will be the result, whereby the shell can be secured, placed upon a polygonal core, and made to turn with the same.

The means for bringing the wooden shell or block l against the revolving saws or cutters to produce an opening or duct similar to that represented in Fig. 9 is clearly illustrated in Figs. l, 2, and 6. As will be seen from an inspection of the said figures, this means comprises a cradle or support consist- Y ing, essentially, of a top piece 53 and a basepiece 54, which are adjustably connected by tie-rods 55 and the nuts 56 on the screw ends of the said rods. Secured to the said top and base pieces by means of the tie-rods 55 or in any other suitable manner are suitably-constructed guides 5S, which are made to partially embrace the tie-rods S and slide against the same, as will be seen from Fig. 6, to properly guide the cradle or support for the shell l and cause the central openings 57 in both the top and base pieces of the said device to pass around the tubular standard when lowered by the means and in the manner to be presently described. Each plate 53 and 54 is provided with suitably-disposed guide portions 59, in which are adjustably secured by means of the set-screws 6l certain angleirons 60, which can be forced against the cutter-surface at the top and bottom of the shell 1, as shown, and then secured in position by means of the set-screws 62. In this manner the said shell or block l can be properly adjusted to have its central cylindrical opening or duct 2 pass directly over the tubular standard and have the teeth of the rapidly-revolving gangs of cutters or saws cut the angular parts 4. (Shown in Fig. 9.)

One means for raising and lowering the cradle or support for the shell l consists in an arrangement of rope or other flexible connection 63, which has its one end passing through an opening (il in the top piece or plate 6 of the apparatus and is secured by means of a ring to the top piece 53 of the cradle or support in which the shell is arranged. The said flexible connection or rope passes over suitable wheels 67 and 68, which are grooved and which rotate in bearings (59 and 70 upon the top 6 or" the apparatus. A weight 66, which is attached to the opposite and free end of the rope or exible connection, serves to counterbalance the weight of the cradle and the shell therein and allows the operator to readily arrange the end of the shell in the cradle upon the gangs of cutters or saws or to easily raise the cradle when the shell has been provided with the longitudinal opening or duct of the shape desired.

Of course it will be understood that I may employ any other suitable means for raising and lowering the cradle and bringing the end of the shell over the tubular standard in contact with the rotary cutters or saws of the apparatus. I am also aware that other changes may be made in the several arrangements and combinations of the various parts, as well as in the details of the construction thereof, without departing from the scope of my present invention. Hence I do not limit my invention to the exact arrangements and combinations of the mechanism as herein described, and illustrated in the accompanying drawings, nor do I confine myself to the exact details of the construction of the parts of the mechanism.
